IMPROVEMENT |N Devices For SURPLYING wl-:FT To THE SHUTTLES IN toonsK '-Spccinmtnim-'ioimng parrtn' LcttensPatcnt No. l 3,556. dated hJuly l2, 1864.

To allvwhom it may conce-rn Beit linown that I, THOMAS INunAM, off Bradford, in the county of York and Kngdorzi of England, have invented new and useful vImprove ments iirLooms for Weaving; and I do hereby declare- 4that the following is a full and exact description thereof', reference being had to the annexed two sheets'of drawings.

The improvements relate to means for ei'- feeting a continuous action in looms, or toav method of supplying weft to y the shuttles 'without stopping the loom for that purpose, whelther thewe-ttbe used up or broken in the sie( .j

-Figures] and 2 are end elevations, and Fig. 3 is a' front elevation of my improved loom. Figs. 4 and 5 aredetail views ofthe shuttle which I employ, shoving that it is formed' with an opening through its sides for a case or box containing a cop ot weft to be' introducedat one side and`expelled at the other. Fig. dis aA section otl the shuttle and cop-case.

lThe ends oi' the cop-case are notched, so

that a spring latch or lock in the shuttle will enter when the case is pushed into the said Shuttle and holditsteady therein untilpushed out'at the oppositesidc by the introduction of another case.

A is the traine-work of the loom; B, the erankshat't, and C the tappet-shai't. D is the Jweft-hammer or lever upon which the weft 'fork E catches when there is no weft in the shd on the beat up of the lay, and F is atappet fixed on the sha-tt (l, which at each lrevolution operates the lever D. G is a 1fach or hopper xed to the frame, so formed as to hold a series of cop-cases one upon another, ready for supply to the shuttles, the bottom 4case being placed exactly opposite the opening in the side of the shuttle when it is in the "shuttle-box and when the lay'or batten is up4 cept when operated as hereinafter explained.

L is a lever carrying the weftfork or wett? feeler, which is txed on av shaft, M, extending.

across the loom, and N is another lever fixed at the other 3nd ot' the. said shaft. 0 is the lay or batten, (carrying thc sliuttle-boxes,) operated by arms or rods from. the crankshaft-gf as usual. P is a tongue' -hinged on the stoprod under the hatten, which is supported upon and rides over a projecting pin, n, on the lever N, and passing under the lever J, as the lay beats ,up when there is a full supply ofweft `in thc shed. Q, is a spout placed behind the shuttle box to receive andconduct .away the' expelled copeases. 1t is a spring-tumbler for actuating a lever, S, (which is also hinged -to the lay), for locking tli'e'"shu,ttle in the shitttle box in a proper position for changing the cop-eases and liberating i'tfa'gain in time f or the pick.

Fig, 7 is a section, through the hopper and shuttle-box on an enlarged scale,y showing more clearly the' means 'of changingthe copA eases or weft-easesg and Fig. 8 is a front View ot'- the shuttlebox with a shuttle and cop-caseloclie'd in proper position for change. y Fig. 9'

is a side elevation vot' the hopper, and Fig. 10 is a sectional plan of the samewith a oop-case therein. showing how it is held until required for the changejbymeans .of sprin-gclamps T, which also forth .guides -i'or the cases from thence tothe shuttle.

The actionotfthis loom is as follows The -hopper is supplied with any connenieiitv number of eopcases, each containing la cop of weft, and the loose ends ofweft are fastened in the clamps H on the breast-beam. .When the weft breaks or becomes used up, the wefttorkacts in the same manner asin ordinary looms, but instead of actua-ting the strapg guide to stop the loom it operates the lever L;

shaft M, andlever N, the' pin n lifting the edd of the tongue P above the inclined foot ot' the lever J, which o n the beat up of the' lay o r hatten is thereby pushed back, The propellerI is simultaneouslydriven forward and drives the bottom cop-casel out of the hopper into the shuttle, (which is at' that time ',txed in proper position in'theshuttle-box by the lock-lever 5;) case (whereinl the' weft broke or was used up) out ofthe shuttle into the spout Q, which conductsit away to be replenished by the attendant'antl replaced in the hopper on the topot' the other cases,l he end ofthe -weft being made The said ease pushesl the otherl fust in the olzunps as hefore.- As one onse is #driven-.out of the hopper the others lower into l position, ready to follow when required.

It will' now be obvious that the object of "this invention is t0 avoid the stoppage of the loom for the supply of weft,'whjioh oooupies it' lconsiderable amount of time and necessarily' subtraots from the effective and beneficial' Working of the loom.' Now, by this inventionv n ostoppage is required for this-purp`ose.

However frequently the weft maybreak, zm-v other cop is supplied on the shuttle getting 'into the b ox, and the. attendant can always keep the hopper supplied with eases contain.

ing weft. I z

It will he seen that the feeding'need not he' limited to the front of the shuttle-box, but may takeplace also from the back, top, orbottonif of the same, as may be de lired.

' I do not connemyself -to the usethe tongue .P for otuziting the propeller fl; but' in some cases I would :tatuato this propeller by a tppet ori-ajmattached to the ,.sheftor 1- t), or by .other equivalent means.'

j Having jthus deiorxbed the nature 'of my' said invention and the manner in whiohlthe l' same isto be performed,[would have it`understood tl iat what I claim is-'J 1. y l e I 1. The combination ofthe lever D with the l lweft-fork E and the leppet F, substantially asaudfor'thelpurpoee set'forth.
